According to Georgejung.org, what happened to Tuna after George got involved in the Medellin Cartel (and eventually got arrested) remains unclear.
Some sources say that he stayed in Mexico for a couple of years. And eventually moved back to Weymouth where he is living until this day. Other sources mention that he got arrested in New England sometime in September 2006. According to this source, he was collecting money for a container of drugs, shipped from Mexico. This source doesn’t mention if he is still in jail or a free man today.
George and Tuna grew up in Weymouth together, but as young adults they moved to Long Beach, California together, where they started dealing drugs. Their business gets very successful when they discover that there is an enormous market for pot (and much higher prices) back at home in Boston.
They start making a lot of money by smuggling drugs from California back to the East Coast. When demand grows, they decide to start buying the drugs directly in Mexico from a local contact.
George Jacob Jung, also known as Boston George, was one of the biggest drug smugglers ever. In the 1970s and early 1980s Jung was a member of the famous Medellin Cartel, which was responsible for over 85 percent of all the drug on the US market. George Jung was the mastermind behind the large scale smuggling of this drug from Colombia to the USA. Read more at Georgejung.org.
